Query regarding snd_pcm_lib_preallocate_pages_for_all()

Query regarding snd_pcm_lib_preallocate_pages_for_all()

[Pharaoh .]

Hi,

I am trying to use snd_pcm_lib_preallocate_pages_for_all() on an arm based
platform for preallocating the DMA buffer.
I am using it as

snd_pcm_lib_preallocate_pages_for_all(pcm,
            SNDRV_DMA_TYPE_DEV,
            NULL,
            64 * 1024, 64 * 1024);

since I dont know what should be passed as the 3'rd param. I tried passing
my device pointer i.e. card->dev after
correctly populating it but I get an error as 'DMA coherent mask in not set'
and buffer is not allocated.

If I pass NULL as shown above, which I think is appropriate, the allocation
is done well and I can play some samples too
using aplay, but when I do a rmmod all hell breaks free.

I am thinking this is corrupting memory some where, since when I preallocate
using SNDRV_DMA_TYPE_CONTINUOUS,
everything works well but I since I need to mmap the buffer I dont use it.

I get following:

Hello,
I have a Mitac 8252D computer with hda_intel, it has 3 sockets in front: 
microphone, audio(headphones)and S/PDIF. 
When using 5.1 the manual says:
Microphone: rear speakers

S/PDIF:	center and subwoofer  
Modprobing without any options gives me sound to the headphone and digital

Modprobing with model=6stack-hp gives me sound to the speakers to but they

For ARM, avoid the present buffer-preallocation and mmap functions in
ALSA core.  Instead you can allocate the buffers directly via normal
dma_alloc_coherent() in your driver.  And, mmap it via
dma_mmap_coherent() by defining the own mmap callback for PCM ops.

See other arm/* drivers for rerecence.

Unfortuantely, no other way, so far.  It's the only way that a driver
can do -- keeping the large chunk as long as it needs.

Yes, I am using my own buffer preallocation scheme now. I allocate a 128K
buffer using dma_alloc_coherent in probe and free it only in remove i.e. at
rmmod time.

I dont think keeping a huge buffer like this till driver removal is a good
idea but when I allocate/deallocate it in hw_params/hw_free respectively, it
is causing fragmentation and sometimes the allocation fails. Do you think
anything better can
be done?

Posting here, at least the content of /proc/asound/codec#*, would be
more helpful.

Is the SPDIF optical?  If yes, the device should have two output pins,
one for SPDIF and one for CLFE.  That'll be relatively easy.
If the SPDIF output is really shared, it means that the digital audio
out widget is used for the analog out, too.  It's not implemented in
other devices, so the change would be somehow unique for this device.

The link he posted is from alsa-info.sh, a script written by wishie on
 #alsa irc and heavily promoted by me.  It has the codec output, as
 well as everything else needed to determine how his system is
 configured.

Actually, a lot of laptops (mine included) have a mini-TOS plug    
 combined with a headphone plug, so it is possible for an optical jack
 and an analog jack to share space.  Plugging in an spdif cable with  
 mini-tos adapter activates the hp-detect routine.  I haven't tested
  spdif output yet (need a good stereo receiver), but that's the
 principle behind it.

I have an iec958 switch that I can use to turn on a red light in the plug 
hole, but it has no effect on if I plug in headphones I can allways hear 
them, allthough somewhat lower than in the headphone jack.
